Coastal Processes

The video explains how coastlines are shaped by three main processes: erosion, transportation, and deposition. Erosion involves the wearing away of land by destructive waves, which can occur through attrition, abrasion, and solution. Transportation refers to the movement of materials along the coast, primarily through longshore drift, which includes solution, suspension, saltation, and traction. Deposition occurs when the sea loses energy and drops the materials it carries, contributing to the formation of diverse coastlines.

What is the primary force behind coastal erosion?

• Constructive waves

• Destructive waves

• Tidal currents

• Wind erosion

Which process involves the zigzag movement of materials along the coast?

• Wave refraction

• Longshore drift

• Swash and backwash

• Tidal flow

How are small particles transported in the water flow?

• Traction

• Saltation

• Solution

• Suspension

What happens when the sea loses energy?

• Transportation speeds up

• Deposition occurs

• Waves become destructive

• Erosion intensifies

Which type of waves are responsible for deposition?

• Destructive waves

• Seismic waves

• Constructive waves

• Tidal waves
